摘　　要：遥感技术的发展为自然生态环境的监测提供了准确、高效的技术手段。基于2018年3月的Landsat数据以及DEM数据,提取了植被覆盖度、土壤指数和坡度三个重要生态因子,并将归一化后的因子带入构建的综合指数评价模型,得出了思茅区生态环境质量指数,最后根据指数值进行分级,对思茅区的自然生态环境质量进行了评价与分析。研究结果表明:思茅区的自然生态环境质量以良和差为主,研究区东北部和东南部的生态环境质量差,西部相对较好。该研究结果与实际情况基本符合,因此基于遥感的自然生态环境监测与评价的方法,能够为区域的生态环境监测、治理和改善提供重要参考。The development of remote sensing technology provides accurate and efficient technical means for monitoring the natural ecological environment. Based on the Landsat data and DEM data in March 2018, the three important ecological factors of vegetation coverage, soil index and slope were extracted, and the normalized factors were brought into the constructed comprehensive index evaluation model, and the Simao district was obtained. Eco-environmental quality index, finally classified according to the index value, to evaluate and analyze the natural ecological environment quality of Simao District. The results of the study show that the quality of the natural ecological environment in Simao District is mainly good and poor, the quality of the ecological environment in the northeast and southeast of the study area is poor, and the west is relatively good. The research results are basically in line with the actual situation. Therefore, the method of natural ecological environment monitoring and evaluation based on remote sensing can provide an important reference for regional ecological environment monitoring, management and improvement.
